• A. $ 70.40
• B. $ 82.00
• C. $ 83.33
• D. $ 86.40

Hint:

To calculate a price after a percentage increase or discount, first apply the percentage to the original price, then adjust by adding or subtracting the result from the original price.

Answer 1

The Correct Option is D

Step 1: Calculate the price after the 20% increase.
The price after the 20% increase is: \[ 96 = 80 + 0.20 \times 80 \] This gives a new price of $ 96.
Step 2: Apply the 10% discount.
The price after applying the 10% discount is: \[ 96 - 0.10 \times 96 = 96 - 9.60 = 86.40 \]
Final Answer: \[ \boxed{86.40} \]
